Featured: Vibrations > Piezoelectric > Vibration Energy Harvesters by MicroGen Systems, Inc. - University of Virginia alumnus Robert Andosca and his Ph.D. Advisor, Professor Junru Wu, have developed a tiny vibration energy scavenging device, half the size of a sugar cube. The "MEMS" device — for microelectromechanical systems — converts mechanical energy into electricity using a special "piezoelectric" material that generates a charge at the slightest jostle.

Featured: Classifieds > Vibrations > Inventor Seeks Best Method to Harness Short Stroke Linear Power - An inventor has a promising technology that produces fluctuations of 5 mm - 2 cm at a frequency of 600 to 3000 vibrations per minute, which can be increased or decreased, along a nominally linear path. In order to both harness the power he's producing with his prototypes as well as to fully validate the technology as a practical, self-loopable overunity system.... (PESWiki; September 19, 2012)

Vibrations / Solid State > Cell Phones Powered by Conversations - Just as speakers transform electric signals into sound, the opposite process -- of turning sound into a source of electrical power -- is possible, according to Scientists from Korea who have turned the main ingredient of calamine lotion into a tiny material that converts sound waves into electricity. Other noise sources such as traffic could also be harnesses for the power grid. (Discovery; Sept. 13, 2010)

Fuel Efficiency / Vibrations > Regenerative shock absorber to bump up car energy capture capabilities - To harvest up and down motion energy usually lost in shock absorbers, a team of mechanical engineers from Stony Brook University, have designed and tested a shock absorber that can be retrofitted to cars to convert the kinetic energy of suspension vibration between the wheel and sprung mass into useful electrical power.

Batteries >M2E Power Could Charge Your Cell Phone With Kinetic Energy! - M2E Power is emphasizing the commercial applications for their technology, with a specific goal: revolutionizing cell phone batteries. An external charger generates between 300 and 700 percent more energy than current kinetic energy technologies, and may eventually replace cell phone batteries altogether. (PESWiki; Aug. 21, 2008)

Zero Point Energy / Vibrations > David Sereda - Zero Point Energy (video) - Discusses his research on differentials, Zero Point Energy, and the hidden harmonic codes of the universe, including prototyping. "There are actual precise harmonic codes which are multiple frequencies working in tandem together," he said. "...It can lead to anything from antigravity to infinite energy."

Wind > Humdinger's Wind Belt Economizes Low Wind Harnessing - Invented by Shawn Frayne, the Windbelt is a taut membrane fitted with a pair of magnets that oscillate between coils. Designed for low wind speeds and budgets, the device is 10x to 30x times more efficient than the best microturbines, and its cost is proportionately small.

Tiny Generator Runs Off Vibrations - Researchers at the University of Southampton, UK, have developed an efficient, sugar-cube-sized electric generator that feeds on environmental vibrations, via the wobbling of several magnets attached to a millimeter-sized cantilever. The device could power small, low-power devices such as wireless sensors or medical implants.

Piezoelectric > Harvesting Energy from Natural Motion - A team at Duke University has come up with at device that is basically a small cantilever with an end magnet that interacts with nearby magnets. The cantilever base is piezoelectric, releasing electrical voltage when strained. By changing the distance of the magnets, the researchers "tune" the interactions of the system with its environment.

Wireless Bridge Sensors Powered by Bridge Vibrations - Clarkson University researchers have developed technology that uses vibrations caused by traffic to power wireless bridge monitor sensors. Electromagnetic generators harvest the natural vibration frequencies of the bridge, resonated each time a car or a truck passed over, even in a different lane. (NewsWise; Oct. 17, 2007)
